Fiber optic sensors for environmental monitoring

Due to decades of neglect as well as ever-increasing industrial activity, environmental monitoring has become an important issue. Given the expense and time constraints associated with classical laboratory analysis, there exists a growing interest in cost-effective and real-time technologies suited to environmental monitoring applications. Recent advances in fiber optic technology and miniaturized optical instrumentation, as well as increasing environmental regulations, are driving an expanded interest in fiber optic sensors for environmental applications. This review of current literature will provide information concerning some of the recent advances in this area.
